在本地一切正常，但是当我这样做时： bundle exec rake assets:precompile 在服务器上，这就是我得到的：

本地环境是 Mac Mountain Lion，服务器是通用 AWS Linux。有任何想法吗？
这是 config/initializers/special_mysql_types.rb 中的内容（迁移文件已在本地正确处理，并且数据库表的创建没有问题）。
ActiveRecord::ConnectionAdapters::Mysql2Adapter::NATIVE_DATABASE_TYPES[:big_int_primary_auto_inc] = "BIGINT(20) UNSIGNED DEFAULT NULL PRIMARY KEY auto_increment"
ActiveRecord::ConnectionAdapters::Mysql2Adapter::NATIVE_DATABASE_TYPES[:big_int_non_primary] = "BIGINT(20) UNSIGNED DEFAULT NULL"
ActiveRecord::ConnectionAdapters::Mysql2Adapter::NATIVE_DATABASE_TYPES[:int_unsigned] = "INT(10) UNSIGNED DEFAULT NULL"
这是我将如何在迁移文件中使用它的示例：
class CreateTweets < ActiveRecord::Migration
def change
create_table :tweets, id: false do |t|
t.column :id, :big_int_primary_auto_inc
t.column :tweet_id, :big_int_non_primary
t.string :tweet_text, limit: 160
end
end
end
这是我的 database.yml 文件：
